Forget the false idea that the pilot suffered ‘night blindness’ climbing out of the soccer stadium: there is ample ambient light from the surrounding built up area to give situational awareness and a solid horizon. After years of similar operations with the AW169 and preceding that the A109 the fearmongering implication of your post is nonsensical.
Checking with AW169 Pilots the departure procedure is absolutely in accordance with the Flight Manual, and raising the gear after 200ft is bog standard checklist stuff.
